I might have missed something, but I couldn't find any matrix 
operations in the multi_array class?!

Further, a MultiArray 'defines an interface to hierarchically 
nested containers'. A matrix is neither really nested nor am I 
too happy with the way of viewing a matrix primarily as a 
container. Technically, of course, it is, but for the 
applications I have in mind it's more important what you can do 
with a matrix as a whole (like adding, multiplying with a scalar 
etc.) rather than their internal structure. That's one reason 
there are no iterators defined yet. They will be important at 
some point for people who want to implement algorithms over 
matrices (or operators for combining matrices with other types 
like vectors), but for now I think the focus should be on 
operations over matrices as a whole.
